Code requires 7th Character Extension identifier. This 7th Character usually captures Episode of Care information, such as "Initial Encounter," "Subsquent Encounter," or "Sequela."ICD Code H40.10 is a non-billable code. To code a diagnosis of this type, you must use specify a 7th character that describes the diagnosis 'unspecified open-angle glaucoma' in more detail. The 7th characters that can be added, and the resulting billable codes, are as follows:
7th Digit | Billable Code | 7th Digit Specifies |
---|---|---|
0 | H40.10X0 | stage unspecified |
1 | H40.10X1 | mild stage |

What is 7th Character Extension?
For codes less than 6 characters that require a 7th character a placeholder 'X' should be assigned for all characters less than 6. The 7th character must always be the 7th position of a code. E.g. The ICD-10-CM code T67.4 (Heat exhaustion due to salt depletion) requires an Episode of Care identifier. T67.4XXA Initial Encounter or T67.4XXD Subsequent Encounter. More InfoThe ICD code H401 is used to code Pseudoexfoliation syndrome
Pseudoexfoliation syndrome (other names: Exfoliation glaucoma, Pseudoexfoliation glaucoma, Pseudoexfoliation of the lens, Exfoliation syndrome), sometimes abbreviated as PEX, is an aging–related systemic disease manifesting itself primarily in the eyes which is characterized by the accumulation of microscopic granular amyloid-like protein fibers. Its cause is unknown, although there is speculation that there may be a genetic basis. It is more prevalent in women than men, and in persons past the age of seventy. Its prevalence in different human populations varies; for example, it is prevalent in Scandinavia. The buildup of protein clumps can block normal drainage of the eye fluid called the aqueous humor and can cause, in turn, a buildup of pressure leading to glaucoma and loss of vision. As worldwide populations become older because of shifts in demography, PEX may become a matter of greater concern.
